I have telephoned and emailed and repeated to report that the filters I recieved were in fact the wrong ones. Twice after calling I have been assured that someone who actually has a clue will phone back and that has not happened nor do I think it will! In conclusion I guess there may not be anyone within your organisation who has a clue. There's certainly no indication that anyone knows about delivering even mediocre customer service. You appear to rely on the customer getting worn down and giving up through lack of engagement on your part. Best of luck with that shitty business model!
